Wetlands of South Africa
Abstract
This contribution briefly reviews the literature on pans in South Africa and synthesises the results, some previously unpublished, of research efforts conducted in the highveld of the Transvaal and Free State on these wetlands. It includes discussions on the definition, distribution, density, and size of pans. Theories on the origin and
maintenance, and the difficulties inherent to the classification of pans are outlined. The abiotic characteristics of these ephemeral systems are examined. In addition, the biotic features of pans, in particular their flora, aquatic invertebrates and birds, but also their fish, amphibians, reptiles and mammals are described. Selected pan systems in the Transvaal and Free State are discussed in detail, in particular the pans in the Lake Chrissie area of the southeastern Transvaal and pans in the western Free State. This analysis incorporates a review of the threats to pans in these regions, including agricultural development, road-building, mining and industrial development, urbanisation, afforestation and the encroachment of alien trees. Research, conservation and management
recommendations are outlined relevant to these ecosystems in South Africa
